EARTHING SYSTEMS
FOR ALL INSTALLATIONS
THE WRICON EARTHING SYSTEM provides the means to locate the entire system completely within the structure, thus providing
a location away from any possibility of accidental damage or unauthorised disconnection.
Safe and effective electrical earthing is the essential requirement of all electrical installations, and the use of reinforced concrete
foundations is an excellent method of achieving this aim.
The WRICON Earthing System permits the installation of an indestructible, totally reliable and constant electrical earth.The heart
of the WRICON Earthing System is the unique Earthing Terminal Plate which allows earthing to the building frame (foundations
or rebar) to be installed easily, simply and very professionally by any person who can weld proficiently. Earthing to the
building frame (foundations or rebar) is permitted under the E.W.R. of New Zealand and the use of WRICON Earthing System
has obvious advantages:-
- Reinforcing steel in concrete foundations provides an indestructible earth electrode.
- WRICON earth lead is safely cast within the concrete and cannot be severed by other trades digging for services.
- CADWELD welded connections (unlike compression connections) do not deteriorate. Additionally, the bronze terminal plate
and insulated earth lead incorporated in the WRICON Earthing System prevent galvanic corrosion and high resistance joints.
- Lower resistance to earth than will be obtained by conventional methods and is much less subject to seasonal changes.

SPECIAL NOTE
Installer to notify local supply authority for inspection of welded
termination to rebar before concrete is poured. |
In a perfect world everyone
would have a perfect earth... |
Now with WRICON they can!
WRICONS ALSO AVAILABLE WITH 2 OR 4 HOLE TERMINAL |
CADWELD CAST GROUND PLATES
CADWELD ground plates used in concrete structures offer convenient ground system connection points.
These ground points are used for equipment, machinery and structure grounding after completion of the concrete work.
The castings are made from a copper alloy...
CADWELD ground plate connections result in current carrying capacity equal to that of a conductor or stud and cannot loosen or corrode.
